Embedded {hardware} and Web of Issues (IoT) specialist Renesas has introduced its first dual-band Wi-Fi 6 and Wi-Fi/Bluetooth Low Vitality (BLE) mixture microcontroller models, concentrating on the IoT and linked dwelling initiatives: the RA6W1 and RA6W2.
“We’re providing our clients the flexibleness to design with a standalone Wi-Fi system, a Wi-Fi/Bluetooth LE combo, or totally built-in modules relying on their wants,” says Renesas’ Chandana Pairla, vice chairman of the corporate’s Connectivity Options Division, of its newest launches. “These wi-fi options save energy, simplify system design and decrease BOM [Bill of Materials] price. With hosted or hostless implementation choices, clients can confidently start their wi-fi onboarding journey and seamlessly combine into next-generation linked techniques.”

Each the RA6W1 and RA6W2 are constructed round an Arm Cortex-M33 microcontroller core operating at as much as 160MHz and with a beneficiant 704kB of static RAM (SRAM), permitting for full impartial operation — although the corporate says they’re additionally appropriate with the corporate’s extensive RA microcontroller vary, working as a networking coprocessor. Each are claimed to be optimized for low-power operation, drawing a claimed 200nA to 4µA in sleep mode and beneath 50µA in Supply Visitors Indication Message (DTIM10) mode.
Connectivity differs relying on which mannequin you select: the RA6W1 has a dual-band 2.4GHz and 5GHz Wi-Fi 6 radio module solely, whereas the RA6W2 provides a Bluetooth Low Vitality (BLE) radio. Each embrace hardware-accelerated AES-256 cryptography, a real random quantity generator (TRNG), and on-the-fly decryption assist with execute-in-place (XiP) for his or her flash storage. Each are additionally Matter 1.4 licensed, the corporate has confirmed.
The RA6W1 is now accessible in FCQFN and WLCSP packages, alongside RRQ61001 and RRQ61051 module variants; the RA6W2 might be launched within the first quarter of subsequent yr in a BGA bundle, Renesas has confirmed. As is common, the corporate has additionally created two reference designs for initiatives constructed utilizing the elements: a human-machine interface (HMI) for sensible houses and an computerized pet door and monitoring system.
